Fluid Dynamics – ENGR 315

CG • Section 8WK • 07/01/2018 to 12/31/2199 • Modified 04/08/2022

Course Description

To provide an understanding of both the kinematics and kinetics of fluids. Students gain knowledge on the fundamental conservation laws of mass, momentum, and energy. Students will be expected to gain an ability to solve and design engineering problems involving pipe flow, turbomachines, pumps, large reservoirs, etc. Topics include: the Reynold’s transport theorem, Bernoulli’s equation, applications of fluid momentum to propellers, wind turbines, turbojets, and rockets, differential fluid flow analysis, dimensional analysis and similitude, Reynolds number and flow classification, analysis and design for pipe flow, flow over external surfaces and boundary layer, cavitation and turbo machines. 

For information regarding prerequisites for this course, please refer to the Academic Course Catalog.


Fluid Dynamics is a primary engineering science that has important applications in engineering fields as well as other disciplines such as medicine and meteorology. Fluid Dynamics builds partially from hydrostatic knowledge obtained in ENGR 235 Statics and from the kinetics learned in ENGR 240 Dynamics. This course is a prerequisite for ENGM 375 Thermal Fluids Design Lab.

Each student will be able to do the following upon successful completion of this course:

  1. Describe the kinematics of fluid motion using Lagrangian and Eulerian description. (SOs: 1, 7)
  2. Derive and apply the fundamental Reynolds Transport Theorem to various types of control volumes. (SOs: 1, 7).
  3. Use Work and Energy methods to derive Bernoulli’s and Energy equations and apply it to cases such as flow from a large reservoir around curved boundary, open channel, closed conduit, Venturi meter, etc. (SOs: 1, 2, 4, 7)
  4. Apply the energy equation in solving engineering problems involving pumps, turbines, and frictional loss. (SOs: 1, 2, 4, 7)
  5. Use the principles of linear and angular momentum to propellers, wind turbines, turbojets, and rockets. (SOs: 1, 2, 4, 7)
  6. Explain the usefulness of computational fluid dynamics in the solution of complex fluid flow. (SOs: 1, 7)
  7. Use the principle of similitude to scale down and solve full-size engineering problems. (SOs: 1, 2, 4, 7)
  8. Classify flows using the Reynolds number and its implications on their analysis. (SOs: 1, 7)
  9. Analyze and design for pipe flow with various fitting and connections. (SOs: 1, 2, 4, 7)
  10. Interpret the concept of boundary layer and its applications on external flow. (SOs: 1, 2, 4, 7)
  11. Explain importance of fluid dynamics in solutions involving biomedical engineering and other contemporary issues. (SOs: 3, 4, 7)
  12. Describe a biblical worldview of Fluid Dynamics and its impact on society. (SOs: 3, 4, 7)
